Abstract

A communications device for separating source signals provided by M signal sources includes an antenna array comprising N elements for forming at least N antenna beams for receiving at least N different summations of the M source signals, with N and M being greater than 2. A controller is connected to the antenna array for selectively forming the at least N antenna beams. A blind signal separation processor forms a mixing matrix comprising up to the at least N different summations of the M source signals. The blind signal separation processor also determines if the different summations of the M source signals are correlated or statistically independent, and if not, then cooperates with the controller for forming different beams for receiving new different summations of the M source signals to replace the different summations of the M source signals that are not correlated or statistically independent in the mixing matrix. The desired source signals are separated from the mixing matrix by the blind signal separation processor.
